Difference between EMF and Potential Difference

The terminology ‘potential difference’ is a very comprehensive term and discovered in so many energy disciplines like electrical and magnetic fields, however, Electromotive Force (EMF) is solely used in the electric circuits. Though, both terms are measured in unit Volts (V), there are significant differences between them. Electromotive force (EMF) …

Difference between Galvanic Cell and Electrolytic Cell

A galvanic cell is the one in which an oxidation-reduction chemical reaction occurs spontaneously to generate electrical energy. Chemical energy is converted into electrical energy. An electrolytic cell is the one in which electrolysis process takes place, a chemical compound is disintegrated by passing electricity through it. The chemical reaction …

Difference between Electric field and Magnetic Field

An Electric field takes place where a voltage exists. They are produced around appliances and cables since a voltage exists. If the voltage is higher, an electric field is stronger and its strength is measured in volts per meter (V/m). The field strength diminishes quickly as we move away from …

Difference between DC Motor and DC Generator

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts …

Difference between Core type and Shell type Transformer

Core type Transformer In core type transformers, winding is positioned on two limbs of the core and there is ONLY one flux path and windings are circumventing the core.     These transformers are quite favorite in High voltage practical applications like Distribution, Power, and Auto-Transformers. Shell Type Transformer In …

Difference between Brushed and Brushless Motors

Brushless DC motors are the one which use an electronic commutation and are powered through a DC source using switching supply and an inverter, which basically generates an AC electrical signal for driving the motor in order to drive the motor. Performance is the main concern for such motors and …

Difference between Capacitor and Battery

Capacitor and battery both perform the same function of storing and releasing an energy, however, there are essential differences between both of them due to how they function differently. Capacitors store energy in the form of an electric field while batteries store energy in the form of chemical energy. The …

Difference between AC Drives and DC Drives

The AC drives operate with AC signal or voltage, for instance, 1-phase or 3-phase AC voltages whereas DC drives operate with DC signal or voltage, for instance, DC supplies, and Batteries. Generally, a DC drive changes an Alternating Current (AC) into Direct Current (DC) using a converter (Rectifier) to operate …
